System for mitigating musculoskeletal stresses from head- related moments exerted on a person

A stress mitigation system for mitigating stresses in a wearer of a headgear, wherein the headgear is configured to apply a load on the wearer that is offset from a center of gravity of a head of the wearer so as to apply a first torque in a first torque direction on the head of the wearer, the stress mitigation system comprising:

• a first force transfer cable segment and a second force transfer cable segment, wherein each force transfer cable segment has a first end and a second end, wherein the first ends are mounted to one of the headgear and the bodywear member and the second ends are mounted to the other of the headgear and the bodywear member, wherein the first ends are laterally inboard from the second ends and are vertically spaced from the second ends such that, during pivoting movement of the head of the wearer in a first pivot direction about a vertical axis, the first force transfer cable segment changes orientation towards a vertical orientation and the second force transfer cable segment changes orientation towards a horizontal orientation, and during pivoting movement of the head of the wearer in a second pivot direction about the vertical axis, the first force transfer cable segment changes orientation towards the horizontal orientation and the second force transfer cable segment changes orientation towards the vertical orientation;
• and
• a tensioning device that is configured to reduce tension in any of the first and second force transfer cable segments that changes orientation towards the horizontal orientation and to increase tension in any of the first and second force transfer cable segments that changes orientation towards the vertical orientation.

A stress mitigation system for mitigating stresses in neck muscles of a person, comprising:

• a headgear configured to mount to the head of the person;
• a track that is mounted to one of the headgear and a bodywear member configured for wearing on a body of the person, wherein the track extends generally laterally;
• a shuttle that is movable along the track;
• and
• a flexible elongate connector that is configured to connect between the shuttle and the other of the headgear and the bodywear member,
• wherein, in a selected position, the flexible elongate connector is biased so as to apply a torque on the headgear in a selected torque direction,
• wherein, when the head of the wearer pivots about a generally longitudinal axis, the shuttle is movable laterally along the track so as to maintain the flexible elongate connector in a substantially longitudinal orientation.
